To all whom it may concern:

Be it known that I, JOHN FOUNTATN, Jr, a citizen of the United States,residing at Elizabeth, inthe county of Union and State of New Jersey,have invented certainnew .and useful Improvements in Junction or OutletBoxes; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it apper-v tains to make and use the same, referencebeing had to the=accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification. v

My invention relates to improvements in junction or outlet boxes to beused in buildings, and desi ned for making connections in the electricalwirinr of buildings. My invention has fuor its object the novelconstruction of an outlet box, comprising a cast metal frame providedwith wrought metal sides, an opening or openings in each of said sides,the openings 1n the wrought metal sides being iilled in one case withcast metal disks and in the otherwith wrou ht metal washers and withcast metal dis s, said disks being integral with the frame and cast insaid openin s simultaneouslyr with the casting of the rame, asdistinguished from boxes heretofore placed on themarket in which thedisks were made of wrought metal and either forced back in'position inthe side by means of a press or cast over said disks during the processof casting the box. In the drawings which accompany this specification,Figure 1 shows a plan view of my improved box, the cover of which hasFig. 2 shows a side eleva- Fig. 3 shows a side elevation in section ofmy improved box, 'taken on line a-b of Fi 1. Fig. 4 shows a fragmentarysectional p an view of my improved box, taken on line of Fig. 2. Iig; 5shows a' side elevation of a modified form of a wrom nt metal side erblankused in my improve box. Fig. ri shows `a lan view of a modifiedform of my improved xox, the cover of which has been removed. Fig. 7shows a side elevation of the box complete. Fig. 8 shows a sideelevation in section of the modified form of my im roved box, takenonvline a-b of Fig. 6, an Fig. 9 shows aside elevation of a wrought metalside or blank with grooves g for the reception of the ends of the plates72,. These plates h are preferabl made of wrought metal and provided witopenings, preferably circular in shape, stamped out in any well knownmanner. The base b is provided with the usual. screw holes t forsecuring position to any part of the building.

j are runners formed on the base '3, 'which registerwith the openings iof the wrought metal plates h, and -the primary object of the runner jis to conduct the molten metal to the openings i, in the said plates hduring the process of casting the base b of 'the outlet box, therebyfilling the openings i with ast metal disks i', which disks, when thebox is cast, form integral arts ofthe box, in view of the fact that saidisks i are cast in the openings i, simultaneously with the frame orbase b. It will be seen thatvany one of the cast metal disks i can bereadily removed from the opening i in the side of the box by the Workmanat the desired point by striking the cast metal disk i a blow with ahammer or similar tool, thereby breaking away the disk i and that partof the runnerg which prothe complete box in jects over the clrcul aropening in back of the plate h.

The attern em loyed in the casting of my out et box is a most identicalin appearance with the box represented in Figi 1, with the exceptionthat side plates having no openings are used in the pattern during themolding 'operatiom The manner of arranging the plates h, which areprovided with the openm s i, in` the sand so as to cast the disk i m saiopening i, as well as the corner posts csecurely around the end edgesreadily understoo and need not be scribed here.

ico

of the plates k will he same material asvthe sides which lare securedings in the side platevof the boxhave'ever integral arts oi the box.y

Y 1. A junction or outlet box comprising a metal sides, each side havinga `series of open- In Fig. 5, I have shown the pla'te h provided wit-hnotches k formed in the ends of i said plate into which the molten metalwill f, also run during the process of casting, thereby'iiorming anadditional positive lock which will prevent accidental disengagement ofthe plates h from the corner posts c;

In Figs. 6,7,- 8 and 9, the wrought metal side plateh is provided withopenings t'. f, Secured in the openings i of the wrought metal sideplate h and held thereinby frictionv are the wrought metal washers i2.The runners j'forined'on the base of the box illustrated in Figs. 6, 7and 8 are extended to register with' lthe openingsi3 oi the wroughtmetalwashers it", and in this particular case, conduct the molten castmetal .to the openings 113 in the wrought metal washers i? to form thecast disks, whichV disks, when the box is'fast, form lt wil be seen`that in the modified form above described, any one of the cast metaldisks can be readily removed lfrom the` wrought metal washers i2 in theside-Voi the box, by striking the cast metal disk 'a blow, with' ahammer,v thereby breaking-the same away from the `wrought metal washer,and providing an opening smaller in diameter than the openings in thebox shown in Figs, 1f ,to 5. Should it be desired for obvious reasos toproduce a larger opening, it will only be necessaiy to remove thewrought metal washers i2 by giving the same a blow with ahammer orsimilar tool. l

I am fully aware that boxes are made with varying numbers'l of closingdisks made ofthe inthe openings of said sides and held therein byfriction or by means of small :tangs and the like; b ut I am not awarethattlie openbeen filled with cast metal, said cast metal bein integralwith and castin said opening simu taneously with the box, capable ofbeing broken away to form an opening =`or open ings in the box for thereception and the di rect attachment thereto of the gas or electricfixtures" employed in the construction oi buildings. i
